Abstract
Treatment fluids, systems, and methods including preparing a multifunctional waste additive (MWA) comprising a cellulose extract derived by contacting a plurality of cigarette filter waste with a solvent; preparing a treatment fluid comprising: a base fluid; an acid; a corrosion intensifier; and the MWA; introducing the treatment fluid into a wellbore drilled through a subterranean formation, the treatment fluid; and allowing the MWA to interact with at least a portion of a metal surface during the introducing.
Claims20
A method comprising:
- preparing a multifunctional waste additive (MWA) consisting of a cellulose extract derived by contacting a plurality of cigarette filter waste with a solvent;
- preparing a treatment fluid comprising:
- a base fluid;
- an acid;
- a terpene corrosion intensifier;
- the MWA,
- wherein the treatment fluid excludes a metal-based corrosion intensifier;
- and
- introducing the treatment fluid into a wellbore drilled through a subterranean formation;
- and
- contacting the treatment fluid with at least a portion of a metal surface during the introducing,
- thereby reducing a corrosion rate of the metal surface by at least about 50% to about 90%, as compared to a corresponding method excluding the MWA.
A system comprising:
- a pump fluidly coupled to a tubular, the tubular extending into a wellbore drilled through a subterranean formation and containing a treatment fluid, the treatment fluid comprising:
- a base fluid;
- an acid;
- a terpene corrosion intensifier;
- and a multifunctional waste additive (MWA) consisting of a cellulose extract derived by solvent extraction of a plurality of cigarette filter waste, wherein the treatment fluid excludes a metal-based corrosion intensifier, and wherein the treatment fluid is capable of reducing a corrosion rate of a metal surface by at least about 50% to about 90%, as compared to a corresponding treatment fluid excluding the MWA.
A method comprising:
- preparing a multifunctional waste additive (MWA) consisting of a cellulose extract derived by contacting a plurality of cigarette filter waste with a solvent;
- preparing a treatment fluid comprising:
- a base fluid;
- an acid;
- and
- the MWA,
- wherein each of the MWA and the treatment fluid exclude a metal-based corrosion intensifier;
- and
- introducing the treatment fluid into a wellbore drilled through a subterranean formation comprising a hydrogen sulfide gas or a precursor thereof;
- and
- contacting the treatment fluid with the hydrogen sulfide gas or the precursor thereof during the introducing, thereby scavenging at least a portion of the contacted hydrogen sulfide gas or any hydrogen sulfide gas generated by the contacted precursor thereof, wherein the scavenging efficiency of the method is about 2 times to about 99 times the scavenging efficiency of a corresponding method excluding the MWA.
